Abstract

This paper discusses a new class of high performance polyethylene-based anion exchange membranes (PE–AEMs) that contain a wide concentration range of pendant (flexible) ammonium chloride (NR3+ Cl–) groups and with or without a cross-linked PE matrix structure. The chemistry involves a metallocene-mediated polymerization of ethylene, silane- protected α, ω-amino-olefin [C x N (SiMe3) 2], with or without styrenic diene (cross-linker), ...
